BACKGROUND

Synthetic latexes are commonly made by emulsion polymerization. Incertain emulsion polymerization processes, monomer compounds aresuspended within an aqueous medium as part of micelles that are formedwith the assistance of a surfactant. The polymerization reactions insuch systems generally proceed by free radical polymerization. When thepolymerization is complete, the resulting polymer can be removed fromthe aqueous medium. Or, in other instances, the resulting dispersion isthe end product.

Emulsion polymerization presents a number of advantages as a method ofmaking certain latexes by free radical polymerization. For example, theprocess allows for rapid polymerization in a temperature-controlledenvironment. Therefore, the properties of the resulting polymer do notchange as the reaction proceeds and heat is generated. Further, emulsionpolymerization permits the reaction medium to retain a near-constantviscosity, which also prevents the properties from changing as thereaction proceeds.

One drawback, however, is that the surfactants that enable thepolymerization remain in the composition following the reaction. Thesesurfactants can be difficult to remove from the polymer composition.Therefore, it may be desirable to discover surfactant compounds thathave a sufficiently low critical micelle concentration and that do notrequire intensive removal efforts following polymerization.

Thus, there is a continuing need to discover novel surfactants that canserve such purposes and improve the properties of the polymers made byemulsion polymerization.

As used herein, the phrases “substituted with one or more . . .” or “substituted one or more times . . . ” refer to a number ofsubstituents that equals from one to the maximum number of substituentspossible based on the number of available bonding sites, provided thatthe above conditions of stability and chemical feasibility are met.

As used herein, “mix” or “mixed” or “mixture” refers broadly to anycombining of two or more compositions. The two or more compositions neednot have the same physical state; thus, solids can be “mixed” withliquids, e.g., to form a slurry, suspension, or solution. Further, theseterms do not require any degree of homogeneity or uniformity ofcomposition. This, such “mixtures” can be homogeneous or heterogeneous,or can be uniform or non-uniform. Further, the terms do not require theuse of any particular equipment to carry out the mixing, such as anindustrial mixer.

As used herein, “optionally” means that the subsequently describedevent(s) may or may not occur. In some embodiments, the optional eventdoes not occur. In some other embodiments, the optional event does occurone or more times.

As used herein, “comprise” or “comprises” or “comprising” or “comprisedof” refer to groups that are open, meaning that the group can includeadditional members in addition to those expressly recited. For example,the phrase, “comprises A” means that A must be present, but that othermembers can be present too. The terms “include,” “have,” and “composedof” and their grammatical variants have the same meaning. In contrast,“consist of” or “consists of” or “consisting of” refer to groups thatare closed. For example, the phrase “consists of A” means that A andonly A is present.

As used herein, “or” is to be given its broadest reasonableinterpretation, and is not to be limited to an either/or construction.Thus, the phrase “comprising A or B” means that A can be present and notB, or that B is present and not A, or that A and B are both present.Further, if A, for example, defines a class that can have multiplemembers, e.g., A₁ and A₂, then one or more members of the class can bepresent concurrently.

As used herein, the various functional groups represented will beunderstood to have a point of attachment at the functional group havingthe hyphen or dash (—) or an asterisk (*). In other words, in the caseof −CH₂CH₂CH₃, it will be understood that the point of attachment is theCH₂ group at the far left. If a group is recited without an asterisk ora dash, then the attachment point is indicated by the plain and ordinarymeaning of the recited group.

As used herein, multi-atom bivalent species are to be read from left toright. For example, if the specification or claims recite A-D-E and D isdefined as —OC(O)—, the resulting group with D replaced is: A-OC(O)-Eand not A-C(O)O-E.

In some instances herein, organic compounds are described using the“line structure” methodology, where chemical bonds are indicated by aline, where the carbon atoms are not expressly labeled, and where thehydrogen atoms covalently bound to carbon (or the C—H bonds) are notshown at all. For example, by that convention, the formula

represents n-propane. In some instances herein, a squiggly bond is usedto show the compound can have any one of two or more isomers. Forexample, the structure can

refer to (E)-2-butene, (Z)-2-butene, or mixtures thereof. In someembodiments, the compounds disclosed herein are generated via olefinmetathesis from natural oils, which can result in scrambling of thestereochemistry around the carbon-carbon double bond, creating a mixtureof E and Z compounds (where R² is not a hydrogen atom). In someembodiments herein, which contain compounds of formula (I) and where R²is not a hydrogen atom, the composition comprises at least 1% by weight,or at least 2% by weight, or at least 5% by weight, or at least 10% byweight, or at least 20% by weight, or at least 35% by weight, or atleast 50% by weight, or at least 65% by weight, or at least 75% byweight, of compounds of formula (I) where the substituents on thecarbon-carbon double bond are in the E (trans) configuration, based onthe total weight of compounds of formula (I) in the composition.

Derivation from Renewable Sources

The compounds employed in any of the aspects or embodiments disclosedherein can, in certain embodiments, be derived from renewable sources,such as from various natural oils or their derivatives. Any suitablemethods can be used to make these compounds from such renewable sources.Suitable methods include, but are not limited to, fermentation,conversion by bioorganisms, and conversion by metathesis.

Olefin metathesis provides one possible means to convert certain naturaloil feedstocks into olefins and esters that can be used in a variety ofapplications, or that can be further modified chemically and used in avariety of applications. In some embodiments, a composition (orcomponents of a composition) may be formed from a renewable feedstock,such as a renewable feedstock formed through metathesis reactions ofnatural oils and/or their fatty acid or fatty ester derivatives. Whencompounds containing a carbon-carbon double bond undergo metathesisreactions in the presence of a metathesis catalyst, some or all of theoriginal carbon-carbon double bonds are broken, and new carbon-carbondouble bonds are formed. The products of such metathesis reactionsinclude carbon-carbon double bonds in different locations, which canprovide unsaturated organic compounds having useful chemical properties.

A wide range of natural oils, or derivatives thereof, can be used insuch metathesis reactions. Examples of suitable natural oils include,but are not limited to, vegetable oils, algae oils, fish oils, animalfats, tall oils, derivatives of these oils, combinations of any of theseoils, and the like. Representative non-limiting examples of vegetableoils include rapeseed oil (canola oil), coconut oil, corn oil,cottonseed oil, olive oil, palm oil, peanut oil, safflower oil, sesameoil, soybean oil, sunflower oil, linseed oil, palm kernel oil, tung oil,jatropha oil, mustard seed oil, pennycress oil, camelina oil, hempseedoil, and castor oil. Representative non-limiting examples of animal fatsinclude lard, tallow, poultry fat, yellow grease, and fish oil. Talloils are by-products of wood pulp manufacture. In some embodiments, thenatural oil or natural oil feedstock comprises one or more unsaturatedglycerides (e.g., unsaturated triglycerides). In some such embodiments,the natural oil feedstock comprises at least 50% by weight, or at least60% by weight, or at least 70% by weight, or at least 80% by weight, orat least 90% by weight, or at least 95% by weight, or at least 97% byweight, or at least 99% by weight of one or more unsaturatedtriglycerides, based on the total weight of the natural oil feedstock.

The natural oil may include canola or soybean oil, such as refined,bleached and deodorized soybean oil (i.e., RBD soybean oil). Soybean oiltypically includes about 95 percent by weight (wt %) or greater (e.g.,99 wt % or greater) triglycerides of fatty acids. Major fatty acids inthe polyol esters of soybean oil include but are not limited tosaturated fatty acids such as palmitic acid (hexadecanoic acid) andstearic acid (octadecanoic acid), and unsaturated fatty acids such asoleic acid (9-octadecenoic acid), linoleic acid (9,12-octadecadienoicacid), and linolenic acid (9,12,15-octadecatrienoic acid).

Metathesized natural oils can also be used. Examples of metathesizednatural oils include but are not limited to a metathesized vegetableoil, a metathesized algal oil, a metathesized animal fat, a metathesizedtall oil, a metathesized derivatives of these oils, or mixtures thereof.For example, a metathesized vegetable oil may include metathesizedcanola oil, metathesized rapeseed oil, metathesized coconut oil,metathesized corn oil, metathesized cottonseed oil, metathesized oliveoil, metathesized palm oil, metathesized peanut oil, metathesizedsafflower oil, metathesized sesame oil, metathesized soybean oil,metathesized sunflower oil, metathesized linseed oil, metathesized palmkernel oil, metathesized tung oil, metathesized jatropha oil,metathesized mustard oil, metathesized camelina oil, metathesizedpennycress oil, metathesized castor oil, metathesized derivatives ofthese oils, or mixtures thereof. In another example, the metathesizednatural oil may include a metathesized animal fat, such as metathesizedlard, metathesized tallow, metathesized poultry fat, metathesized fishoil, metathesized derivatives of these oils, or mixtures thereof.

Such natural oils, or derivatives thereof, can contain esters, such astriglycerides, of various unsaturated fatty acids. The identity andconcentration of such fatty acids varies depending on the oil source,and, in some cases, on the variety. In some embodiments, the natural oilcomprises one or more esters of oleic acid, linoleic acid, linolenicacid, or any combination thereof. When such fatty acid esters aremetathesized, new compounds are formed. For example, in embodimentswhere the metathesis uses certain short-chain olefins, e.g., ethylene,propylene, or 1-butene, and where the natural oil includes esters ofoleic acid, an amount of 1-decene and 1-decenoid acid (or an esterthereof), among other products, are formed. Followingtransesterification, for example, with an alkyl alcohol, an amount of9-denenoic acid alkyl ester is formed. In some such embodiments, aseparation step may occur between the metathesis and thetransesterification, where the alkenes are separated from the esters. Insome other embodiments, transesterification can occur before metathesis,and the metathesis is performed on the transesterified product.

In some embodiments, the natural oil can be subjected to variouspre-treatment processes, which can facilitate their utility for use incertain metathesis reactions. Useful pre-treatment methods are describedin United States Patent Application Publication Nos. 2011/0113679,2014/0275595, and 2014/0275681, all three of which are herebyincorporated by reference as though fully set forth herein.

In some embodiments, after any optional pre-treatment of the natural oilfeedstock, the natural oil feedstock is reacted in the presence of ametathesis catalyst in a metathesis reactor. In some other embodiments,an unsaturated ester (e.g., an unsaturated glyceride, such as anunsaturated triglyceride) is reacted in the presence of a metathesiscatalyst in a metathesis reactor. These unsaturated esters may be acomponent of a natural oil feedstock, or may be derived from othersources, e.g., from esters generated in earlier-performed metathesisreactions. In certain embodiments, in the presence of a metathesiscatalyst, the natural oil or unsaturated ester can undergo aself-metathesis reaction with itself.

In some embodiments, the metathesis comprises reacting a natural oilfeedstock (or another unsaturated ester) in the presence of a metathesiscatalyst. In some such embodiments, the metathesis comprises reactingone or more unsaturated glycerides (e.g., unsaturated triglycerides) inthe natural oil feedstock in the presence of a metathesis catalyst. Insome embodiments, the unsaturated glyceride comprises one or more estersof oleic acid, linoleic acid, linoleic acid, or combinations thereof. Insome other embodiments, the unsaturated glyceride is the product of thepartial hydrogenation and/or the metathesis of another unsaturatedglyceride (as described above).

The conditions for such metathesis reactions, and the reactor design,and suitable catalysts are as described below with reference to themetathesis of the olefin esters. That discussion is incorporated byreference as though fully set forth herein.

Olefin Metathesis

In some embodiments, one or more of the unsaturated monomers can be madeby metathesizing a natural oil or natural oil derivative. The terms“metathesis” or “metathesizing” can refer to a variety of differentreactions, including, but not limited to, cross-metathesis,self-metathesis, ring-opening metathesis, ring-opening metathesispolymerizations (“ROMP”), ring-closing metathesis (“RCM”), and acyclicdiene metathesis (“ADMET”). Any suitable metathesis reaction can beused, depending on the desired product or product mixture.

In some embodiments, after any optional pre-treatment of the natural oilfeedstock, the natural oil feedstock is reacted in the presence of ametathesis catalyst in a metathesis reactor. In some other embodiments,an unsaturated ester (e.g., an unsaturated glyceride, such as anunsaturated triglyceride) is reacted in the presence of a metathesiscatalyst in a metathesis reactor. These unsaturated esters may be acomponent of a natural oil feedstock, or may be derived from othersources, e.g., from esters generated in earlier-performed metathesisreactions. In certain embodiments, in the presence of a metathesiscatalyst, the natural oil or unsaturated ester can undergo aself-metathesis reaction with itself.

In some embodiments, the metathesis comprises reacting a natural oilfeedstock (or another unsaturated ester) in the presence of a metathesiscatalyst. In some such embodiments, the metathesis comprises reactingone or more unsaturated glycerides (e.g., unsaturated triglycerides) inthe natural oil feedstock in the presence of a metathesis catalyst. Insome embodiments, the unsaturated glyceride comprises one or more estersof oleic acid, linoleic acid, linoleic acid, or combinations thereof. Insome other embodiments, the unsaturated glyceride is the product of thepartial hydrogenation and/or the metathesis of another unsaturatedglyceride (as described above).

The metathesis process can be conducted under any conditions adequate toproduce the desired metathesis products. For example, stoichiometry,atmosphere, solvent, temperature, and pressure can be selected by oneskilled in the art to produce a desired product and to minimizeundesirable byproducts. In some embodiments, the metathesis process maybe conducted under an inert atmosphere. Similarly, in embodiments wherea reagent is supplied as a gas, an inert gaseous diluent can be used inthe gas stream. In such embodiments, the inert atmosphere or inertgaseous diluent typically is an inert gas, meaning that the gas does notinteract with the metathesis catalyst to impede catalysis to asubstantial degree. For example, non-limiting examples of inert gasesinclude helium, neon, argon, and nitrogen, used individually or in witheach other and other inert gases.

The reactor design for the metathesis reaction can vary depending on avariety of factors, including, but not limited to, the scale of thereaction, the reaction conditions (heat, pressure, etc.), the identityof the catalyst, the identity of the materials being reacted in thereactor, and the nature of the feedstock being employed. Suitablereactors can be designed by those of skill in the art, depending on therelevant factors, and incorporated into a refining process such, such asthose disclosed herein.

Rev.,2009, 109, 3211-3226, each of which is incorporated by reference hereinin its entirety, except that in the event of any inconsistent disclosureor definition from the present specification, the disclosure ordefinition herein shall be deemed to prevail.

In certain embodiments, the metathesis catalyst is dissolved in asolvent prior to conducting the metathesis reaction. In certain suchembodiments, the solvent chosen may be selected to be substantiallyinert with respect to the metathesis catalyst. For example,substantially inert solvents include, without limitation: aromatichydrocarbons, such as benzene, toluene, xylenes, etc.; halogenatedaromatic hydrocarbons, such as chlorobenzene and dichlorobenzene;aliphatic solvents, including pentane, hexane, heptane, cyclohexane,etc.; and chlorinated alkanes, such as dichloromethane, chloroform,dichloroethane, etc. In some embodiments, the solvent comprises toluene.

In other embodiments, the metathesis catalyst is not dissolved in asolvent prior to conducting the metathesis reaction. The catalyst,instead, for example, can be slurried with the natural oil orunsaturated ester, where the natural oil or unsaturated ester is in aliquid state. Under these conditions, it is possible to eliminate thesolvent (e.g., toluene) from the process and eliminate downstream olefinlosses when separating the solvent. In other embodiments, the metathesiscatalyst may be added in solid state form (and not slurried) to thenatural oil or unsaturated ester (e.g., as an auger feed).

The metathesis reaction temperature may, in some instances, be arate-controlling variable where the temperature is selected to provide adesired product at an acceptable rate. In certain embodiments, themetathesis reaction temperature is greater than −40° C., or greater than−20° C., or greater than 0° C., or greater than 10° C. In certainembodiments, the metathesis reaction temperature is less than 200° C.,or less than 150° C., or less than 120° C. In some embodiments, themetathesis reaction temperature is between 0° C. and 150° C., or isbetween 10° C. and 120° C.

EXAMPLES Example 1—Synthetic Procedure

Into a 1 liter 3-necked round-bottomed flask equipped with a stir bar,thermocouple, Dean-Stark trap, condenser, glass stopper, heating mantle,and nitrogen inlet was added the fatty acid (9-decenoic acid, 9-DA, 75.0g, 0.440 mol). To this was added an equal molar amount of the methoxypolyethylene glycol (Carbowax™ 550, 252 g, 0.440 mol), toluene (325 g),and p-toluene sulfonic acid (pTsOH, 1.0 g). This was stirred (500 RPM)and heated to reflux (118 to 124° C.). Heating was continued until thetheoretical amount of water was collected in the Dean-Stark trap (7.9ml), usually after 8 hours. The water was drained from the Dean-Starktrap and the reaction continued (8 h) until no more water accumulated(<1.0 ml). During this time the reaction darkened to a yellow-orangecolor. Heating was discontinued and the cooled (60° C.) solution wastransferred into a 2 liter pear-shaped flask and concentrated in vacuo(95° C./full vacuum). The hot product (uC10MEE-12EO) was neutralized,transferred into a tared eight ounce clear bottle, and weighted(quantitative yield). Using a similar procedure, 7EO and 16EO variantsof the same ester were made.

Example 2—Foam Height

The 9-decenoic acid methyl ester ethoxylates (uC10MEE-XXEO) demonstratesignificantly lower foam generation than their saturated counterparts(C10MEE-XXEO), and lower foaming relative to commercial alkylphenolethoxylates (Table 1). Mitigation of surfactant-driven foaming is animportant trait that can impact the quality of finished coatings. Table1 shows foam height results using the Ross-Miles foam height method.

Example 3—Polymerization

9-Decenoic acid methyl ester ethoxylates show improved handlingcharacteristics relative to their saturated C10 counterparts. Manynonionic surfactants form intractable (gel) liquid crystalline phaseswith increasing aqueous concentration. This can be a significantlimitation not only in the preparation and transfer aqueous productscontaining these surfactants, but in maintaining their stability overprolonged periods. Methyl ester ethoxylates derived from 9-decenoic acidshowed no gel phase formation and lower viscosity than decanoic acidmethyl ester ethoxylates (Table 2). This is vastly improved relative tothe linear and other saturated alcohol ethoxylates used in lieu of APEs.Table 2 shows the Brookfield viscosity as a function of aqueousconcentration at 25° C.

Example 4—Polymerization

Into a 250 ml 4-necked round-bottomed flask (RBF) equipped with a stirbar, thermocouple, condenser, two rubber septa, hot water bath, andnitrogen inlet were added deionized (DI) water (45.6 g) and sodiumcarbonate (0.08 g). This was stirred (250 RPM) and warmed to 70° C.while nitrogen was being bubbled to degas the water. After 10 minutes,the nitrogen bubbling was discontinued and the anionic surfactant(PolyStep™ B-27, 2.4 g) was added followed by the nonionic surfactant(uC10MEE-12EO, 0.41 g) to obtain an HLB of 20.5. Separately, butylacrylate (9.0 g, 20 wt %) was mixed with vinyl acetate (36.0 g, 80 wt %)and added to a 50 ml glass syringe. A solution of potassium persulfate(0.040 g) was dissolved into DI water (1.0 g) and placed into a 1 mlglass syringe. Another solution of potassium persulfate (0.05 g) withsodium carbonate (0.10 g) was dissolved into DI water (6 ml) and placedinto a 5 ml glass syringe. The monomers were fed into the RBF by asyringe pump and the initial charge of the potassium persulfate solution(1.0 g) was added to the stirred surfactant solution. After 10 minutes,the other solution of initiator (6 ml) was pumped in and the reactiontemperature held at 70° C.+/−2° C. The monomer feed was complete after 2h, the initiator feed finished a half hour later and the reaction washeld at 70° C. for an additional hour. Heating was discontinued and thelatex was poured through a 600 micron screen to remove any coagulum. Thecoagulum was added to the residue in the flask and dried (1.9 g). Thewhite latex was weighted (92.6 g) and its percent solids determined(46.9 wt %, 43.4 g solids) to afford a 97.8% mass balance.
